Maybe it's the way your browser is displaying text and font sizes? Here is what I see with Safari, similar with Firefox:

There's a big "Re: title" heading between two consecutive posts.

Can you show a sample thread, where we can see this? With my browser, I see only the inline image. It's here in this thread with the forum posting screenshot, also fine for example in: Intersection between two curves 3D. Perhaps that post, where you noticed, has something specific different issue.
